MPC5744P sys_clk cann't config to 200Mhz

like the appendix m5744xinit.c,i config the PLL1 to 200Mhz.And i config the MC_ME.RUN0_MC.R to choose sys_clk=PLL1=200Mhz.

And in main(void),i use SIUL_ToggleIO(SIUL_PD5) to observe the time of system running time.But i found that the time of SIUL_PD5 togglling is 120us.So i calculated the time of sys_clk,it seems to be 40Mhz not 200Mhz.

I really don't know why the program within the main function runs so slowly?

Do you see the The attachment I uploaded？I relly config the clock to 200Mhz as the excel tool for clock configuration.But the speed of instructions running is not 200Mhz,it runs too slowly just like that the speed is 40Mhz.

And also there is another problem,when i debug this instructions->"MC_CGM.SC_DC0.R = 0x00030000;".the mpc5744 can't debug program any more.The reset signal is 0 all the time.There is any advice to solve this problem?
